Blok Cepu

Blok Cepu

The Cepu Block Mining Working Area covers 919.19 km2 (91,120 ha), spanning two regions: Bojonegoro Regency in East Java Province and Blora Regency in Central Java Province. Exploration activities in the Cepu Block have yielded oil and gas discoveries in six structures: Cendana, Banyu Urip, Jambaran, Kedung Keris, Alas Tua West, and Alas Tua East. The Cepu Block PSC commenced commercial oil production on August 31, 2009. The Cepu Production Sharing Contract (PSC) was signed on September 17, 2005, covering the Cepu contract area in Central and East Java by ExxonMobil Cepu Limited (EMCL), Ampolex Cepu Pte Ltd, PT Pertamina EP Cepu, and four Regionally-Owned Enterprises: PT Asri Dharma Sejahtera (Bojonegoro), PT Petrogas Jatim Utama Cendana (East Java), PT Blora Patragas Hulu (Blora), and PT Sarana Patra Hulu Cepu (Central Java), all of which are contractors under the Cepu PSC. The Cepu PSC will continue until 2035. A Joint Operating Agreement (JOA) has been signed by the contractors, with ExxonMobil acting as the operator of the Cepu PSC on behalf of the contractors.

Oil produced in the Block's working area is processed at the Central Processing Facility (CPF). Crude oil delivery pumps will be located at the CPF to transport crude oil to the offshore Floating Storage and Offloading (FSO) facility via the Tuban Coastal Facility. This facility includes pigging equipment for both onshore and offshore pipelines, and is equipped with communications equipment to support smooth operations and system monitoring.

The four BUMDs are PT Asri Dharma Sejahtera (ADS) as the BUMD of Bojonegoro Regency, PT Petrogas Jatim Utama Cendana (PJUC) as the BUMD of East Java Province, PT Blora Patragas Hulu (BPH) as the BUMD of Blora Regency, and PT Sarana Patra Hulu Cepu (SPHC) as the BUMD of Central Java Province. Through the BKS, these four BUMDs collectively manage the rights and obligations of the 10% PI, conduct joint supervision of operations with the Cooperation Contract Contractor (KKKS), and ensure that governance, lifting, and commercialisation of oil are carried out professionally so that the economic benefits of the Cepu Block can be optimised for the region.
